I have a Maxtor hard drive that I want to install as a second drive for storing data. I have set the original drive to master and when going to set the second drive to slave, I noticed that it is marked MS, CS, and CA (or CAI)? What does the CA stand for? I tried to jumper the second drive on CA, but it wouldn't recognize the drive. I have edited the BIOS and changed the drives to auto. Any suggestions as to why this drive is not being recognized?
